ABSTRACT
Objective To investigate the changes and clinical significance of serum thymidine kinase 1(TK1) ,carbohydrate antigen 153 (CA153) and carcinoembryonic antigen(CEA) in the patients with breast cancer .Methods The levels of serum TK1 ,CA153 and CEA were detected in 92 inpatients with breast cancer ,66 patients with benign breast disease and 50 people undergoing the physical examination . The relationship between serum TK1 ,CA153 and CEA with the pathologic parameters in breast cancer was analyzed by the single factor a‐nalysis method .Results Serum TK1 ,CA153 and CEA levels in the breast cancer group were significantly higher than those in the benign breast disease group and control group ,the differences were statistically significant(P<0 .05) .The serum TK1 ,CA153 and CEA levels were related with the degree of pathological stage and lymph node metastasis(P<0 .05) .Conclusion The increase of serum TK1 ,CA153 and CEA levels has an important clinical significance in the diagnosis ,infiltration ,metastasis and severity of breast cancer .
ABSTRACT
Objective To investigate the diagnostic significance of lysophosphatidic acid (LPA) ,tumor specific growth factor (TSGF) and carbohydrate antigen 153 (CA153) in breast cancer .Methods Serum levels of LPA ,TSGF and CA153 were detected in 97 cases of breast cancer (cancer group) ,43 cases of benign breast disease (benign group) and 50 healthy females (control group) .Diagnostic significances of these parameters were analyzed .Results Serum levels of LPA ,TSGF and CA153 in cancer group were significantly higher than benign group and control group (P<0 .05) .Diagnostic sensitivity and specificity of combined detection of LPA ,TSGF and CA153 was higher than individual testing (P<0 .05) .Conclusion Combined detection of tumor mark‐ers could improve the diagnostic specificity and sensitivity of breast cancer ,and provide reliable experimental basis for diagnosis .
ABSTRACT
Objective To evaluate the differential diagnostic values of combined detection of adenosine de aminase (ADA),carcinoembryonic antigen (CEA),carbohydrate antigen 153 (CA153),neuron-specific enolase (NSE) and carbohydrate antigen 199 (CA199) in patients with pleural effusion.Methods Serum and hydrothorax fluid of CEA,CA153,NSE and CA199 in patients with plearal effusion were measured by electrochemiluminescence assay(ECLA),ADA from pleural effusions were measured by enzyme rate assay,and the clinical value of combined detection in the differential diagnosis of pleural effusion was evaluated.Results The levels of ADA(65.89±19.81 U/L) in hydrothorax fluid group with tuberculous pleural effusion were beth higher than those in the groups with inflammatory pleural effusion (17.33±16.58) U/L and malignant pleural effusion(27.44±22.64) U/L (q=12.19 and 10.72,P＜0.01).The positive rate of A DA was 82.88% (29/135) in hydrothorax fluid group with tuberculous pleural effusion,13.41% (11/135) in malignant pleural effusion and 11.11% (2/135) in inflammatory pleural effusion (X~2=59.07,P＜0.01).The levels and positive rate of CEA,CA153,NSE,and CA199 in serum and hydrothorax fluid group with malignant pleural effusion were both higher than those in the group with tuberculous pleural effusion (P＜0.05).Compared with the group with malignant pleural effusion,the levels of CA153 and CA199 in serum and the levels and the positive rate of NSE in serum and hydrothorax fluid were not statistically different in inflammatory pleural effusion group.In the 82 cases with malignant pleural effusion,the positive rate of the four kinds of serum tumor markers including CEA,CA153,NSE and CA199 was 74.39% (61/82) and the positive rate of those hydrothorax fluid tumor markers was 82.93% (68/82).Conclusions Combined detection of ADA,CEA,CA153,NSE and CA199 is of some significance to the differential diagnosis of pleural effusion.
